Technical Field
[0001] The utility model relates to the technical field of platform scales, and particularly relates to a new type of adjustable electronic platform scale. Background Art
[0002] Most of the existing electronic scales are designed with a fixed tabletop, and the tabletop area is limited. When weighing items with a relatively large volume but within the weighing range, they often seem powerless. Although some electronic scales on the market have solved this problem by adding additional trays or extension plates, these designs are often complex in structure, inconvenient to operate, and prone to affecting the accuracy and stability of weighing. Therefore, it is of great significance to develop an adjustable electronic platform scale with a simple structure, easy adjustment, and good stability. Summary of the Utility Model
[0003] The utility model aims to provide a new type of adjustable electronic platform scale, aiming to solve the problems that the tabletop of the existing electronic scale is not adjustable and inconvenient to use when weighing items of different sizes, and improve the practicability and flexibility of the electronic scale by designing an adjustable tabletop structure.
[0004] To achieve the above object, the following scheme is adopted in the utility model:
[0005] A new type of adjustable electronic platform scale includes a base, a weighing sensor, and a weighing platform arranged in sequence from bottom to top. A vertical rod is connected to the base through a rotating device. A display is connected to the top of the vertical rod. A control device is arranged between the bottom of the vertical rod and the base. An adjustment mechanism is arranged on the weighing platform;
[0006] The adjustment mechanism includes a motor and a slide bar. An edge bar is vertically connected to the outer end of the slide bar away from the motor. The slide bar is movably arranged in a chute opened on the weighing platform. A tooth row is arranged on the slide bar and meshes with a gear installed on the output shaft of the motor for transmission;
[0007] A switch is arranged in the control device and is connected to the forward and reverse control circuits of the motor.
[0008] Further, the control device includes a fixed base and two stoppers connected to the periphery of the vertical rod. Two switches are arranged on the base. The stoppers and the switches are in one-to-one correspondence. The vertical rod is connected to the base or the base through a tension elastic member; when the length of the tension elastic member is the shortest, the stopper and the switch do not contact, and the switch is in an off state.
[0009] Further, a row of slide bars is arranged on each side of the central axis of the motor. One row of slide bars is connected to the gear through a tooth row above the gear, and the other row of slide bars is connected to the gear through a tooth row below the gear.
[0010] Further, the number of the side bars is two and they are oppositely arranged on both sides of the weighing platform.
[0011] Further, one of the switches is connected to the forward rotation circuit of the motor, and the other is connected to the reverse rotation circuit of the motor.
[0012] Further, the rotating device is a bearing.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0023] Such as Figures 1 to 5As shown in the figure, a new type of adjustable electronic platform scale includes a base 1, a weighing sensor 2, and a weighing platform 3 arranged in sequence from bottom to top. The weighing sensor 2 is connected to the base 1 and the weighing platform 3. A vertical rod 1a is connected to the base 1 through a rotating device. The rotating device is a bearing, so the vertical rod 1a can rotate on the base 1. The top of the vertical rod 1a is connected to a display 1b, and the display 1b is used to display the weighing result. A control device 4 is arranged between the bottom of the vertical rod 1a and the base. An adjusting mechanism 5 is arranged on the weighing platform 3. The adjusting mechanism 5 realizes a tabletop structure with adjustable size, enabling the electronic scale to easily handle items of different sizes.
[0024] Specifically, the adjusting mechanism 5 includes a motor 5a and a slide bar 5b. An edge bar 5c perpendicular to the slide bar 5b is arranged at the outer end of the slide bar 5b away from the motor 5a. The number of edge bars 5c is two and they are arranged oppositely on both sides of the weighing platform 3. The slide bar 5b is movably arranged in a chute opened on the weighing platform 3. A tooth row is arranged on the slide bar 5b and meshes with a gear installed on the output shaft of the motor 5a for transmission. On both sides of the central axis of the motor 5a, there is a row of slide bars 5b of the same height. One row of slide bars 5b is connected to the gear through a tooth row above the gear, and the other row of slide bars 5b is connected to the gear through a tooth row below the gear. When the motor 5a rotates forward, the two edge bars 5c move away from the weighing platform 3, and the weighing platform 3 expands. When the motor 5a rotates in reverse, the two edge bars 5c move closer to the weighing platform 3, and the weighing platform 3 shrinks, with easy adjustment.
[0025] To control the adjusting mechanism 5, a switch 4b is arranged in the control device 4 and is connected to the forward and reverse control circuits of the motor 5a. The control device 4 includes a fixed base 4a and two stoppers 4c connected to the periphery of the vertical rod 1a. Two switches 4b are arranged on the base 4a, and the positions of the stoppers 4c correspond to those of the switches 4b one by one. The vertical rod 1a is connected to the base 4a or the base 1 through a tension elastic member 4d. The tension elastic member 4d is a tension spring to realize the reset of the vertical rod 1a after being twisted. When the length of the tension elastic member 4d is the shortest, the stopper 4c does not contact the switch 4b, and the switch 4b is in the off state. When the vertical rod 1a is rotated to drive the stopper 4c to move, one of the stoppers 4c contacts the corresponding nearest switch 4b, and the external mechanical force will cause the moving contact at the end of the action reed of the switch 4b to close with the fixed contact, thus realizing the connection of the circuit. Specifically, as Figure 6 shown, one switch 4b is connected to the forward rotation circuit of the motor 5a, and the other is connected to the reverse rotation circuit of the motor 5a. The forward and reverse rotation of the DC motor is controlled by changing the current direction, and the two switches 4b will not be turned on simultaneously.
[0026] When using a new type of adjustable electronic platform scale of the present utility model, according to the size of the item to be weighed, twist the vertical rod 1a to turn on the control switch 4b. When the motor 5a rotates forward, the two side bars 5c move away from the weighing platform 3, and the weighing platform 3 expands. When the motor 5a rotates in reverse, the two side bars 5c move towards the weighing platform 3, and the weighing platform 3 shrinks, enabling the electronic scale to easily handle items of different sizes and improving the convenience and practicality of use.
[0027] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those of ordinary skill in the art, any changes, modifications or additions made without departing from the concept of the present utility model are all covered within the protection scope of the present utility model.
